So I followed your install directions, was exactly what I had done previously before I posted this question.
In my preferences I copied my sketch book location;
Then I closed it and quit Arduino 1.8.51.0 and went to that location.
Found my Tools directory, downloaded said file in that directory,
when all was done, I did have the file structure as you described ,same as before.
I opened my Arduino Ide program, selected Tools and that structure for the ESP8266LittleFSDataDownload does not show up.
